Siberia dating site

Lake El’gygytgyn is situated in a 3.6 Ma old impact crater in north-eastern Siberia and probably represents one of the most complete archives of Arctic climate change.Investigated here is the potential of infra-red stimulated luminescence (IRSL) using the single-aliquot regenerative-dose (SAR) approach for dating sediments from this lake.The modelled water content for the entire time of burial is seen as the most prominent uncertainty at this particular site.Despite these potential error sources, SAR-IRSL ages are in acceptable agreement with the given timeframe and clearly point to the possibility to establish independent chronologies at this site up to at least 400,000 years.Archeologist Andrey Gusev, from the Scientific Research Centre of the Arctic in Salekhard, said the plates of armour found at the site are all made from reindeer antlers.'There are about 30 plates in the collection of Ust-Polui,' he said.

Dr , senior researcher at the Institute of Geology and Mineralogy in Novosibirsk, said: 'If there was previously no doubt that the bones and teeth belonged to this species, the question of the age of the finds remained open until recently.' The discovery shows the so-called quill pig 'living far beyond its current range', with the closest habitat now India.

Independent age control is available from a published age model of a parallel core that is based on tuning sediment proxies with regional insolation and the results of previous multiple aliquot IRSL dating.

Although the site is located within volcanic bedrock, anomalous fading seems to have little effect on the calculated ages.

It is based on a nordic bath circuit and thermal therapy. Benefits of Nordic Bath Circuit This facility is clean, modern, and well maintained.

  1. Desmond Clark (1979:7) observed that without radiocarbon dating "we would still be foundering in a sea of imprecisions sometime bred of inspired guesswork but more often of imaginative speculation." And as Colin Renfrew (1973) aptly noted over 30 years ago, the "Radiocarbon Revolution" transformed how archaeologists could interpret the past and track cultural changes through a period in human history where we see among other things the massive migration of peoples settling virtually every major region of the world, the transition from hunting and gathering to more intensive forms of food production, and the rise of city-states.
